Journey fit
Spend governance sits in Operate because it matters after agents are live and recurring costs need iteration, not just initial build. Budget tracking and spend approval loops support ongoing tuning of how much your agents are allowed to burn.
How it compares
Agent finance control plane MCP, not a revenue analytics or marketing attribution skill.
